Unmatched Rear Suspension Control

Upgrade your Ram 1500 (2009–Present) with the Trail Series Adjustable Rear Control Arm Set, engineered to eliminate wheel hop, enhance traction, and provide precise axle alignment. Designed for daily drivers, off-road enthusiasts, and towing applications, this set ensures your rear suspension operates at peak performance, no matter the terrain.

What’s Included?

  • Trail Series Adjustable Rear Upper Control Arms (TRL-R-15-2009-RU2)
  • Trail Series Adjustable Rear Lower Control Arms (TRL-R-15-2009-RL2)

Key Features Benefits

  • Heavy-duty DOM tubing construction – Built from 1.75" OD, .313" wall DOM tubing for maximum strength and durability.
  • Polyurethane Johnny Joint combo – Features high-grade polyurethane bushings at the fixed ends for reduced NVH (Noise, Vibration, and Harshness) and RockJock Johnny Joints at the adjustable ends for maximum articulation and flexibility.
  • Full adjustability for optimal suspension control – Designed to fine-tune rear axle positioning for pinion angle correction, improved traction, and a smoother ride.
  • Recommended pairing – For total rear-end stability and complete axle alignment, pair with the Trail Series Adjustable Rear Panhard Track Bar (TRL-R-15-2009-RPTB1) to ensure precise suspension geometry and eliminate lateral axle shift.

Eliminate Wheel Hop Maintain Axle Stability

Factory control arms allow unwanted axle movement, leading to wheel hop, traction loss, and uneven tire wear. By replacing them with fully adjustable upper and lower control arms, you gain control over axle positioning, ensuring power is transferred efficiently to the ground. Pairing these arms with an adjustable track bar optimizes suspension geometry, creating a balanced, high-performance rear end.

Highly Durable Two-Stage Powder Coating

All components undergo a two-stage powder coating process for maximum durability and corrosion resistance. The zinc primer base coat provides superior rust protection, while the durable topcoat is available in 10 color options for a customized look.

Optional Hardware Upgrade

This control arm set is designed for installation using factory hardware, but for enhanced durability and a more secure installation, we offer an optional Grade 8 hardware kit (sold separately).

Proudly Made in the USA

Manufactured in Orem, UT, every CORE 4X4 component meets strict quality control standards for precision, strength, and long-term durability.

Final Thoughts

The Trail Series Adjustable Rear Control Arm Set is a must-have upgrade for Ram 1500 owners looking for improved suspension performance, better handling, and enhanced stability. By combining adjustable control arms with an adjustable track bar, you gain complete control over axle positioning, ensuring your truck stays planted in all driving conditions. Upgrade today and experience the difference in traction, handling, and suspension control!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!
